摘要： A substrate (5) is located within a deposition chamber (2), the substrate defining a substrate plane. A barrier plate (6) is disposed in spaced relation above the substrate and substantially parallel thereto, the area of said barrier plate in a plane parallel to said substrate being substantially equal to said area of said substrate in said substrate plane, i.e. within 10 % of said substrate area. The barrier plate has a smoothness tolerance of 5 % of the average distance between said barrier plate and said substrate. A mist (66) is generated, allowed to settle in a buffer chamber (42), filtered through a 1 micron filter (33), and flowed into the deposition chamber between the substrate and barrier plate to deposit a liquid layer on the substrate. The liquid is dried to form a thin film (1130) of solid material on the substrate, which is then incorporated into an electrical component (1112) of an integrated circuit (1110).

摘要： A xylene exchange (P44) is performed on a stock solution of BST of greater than 99.999 % purity dissolved in methoxyethanol, and a carboxylate of a dopant metal, such as magnesium 2-ethylhexanoate is added to form a precursor. The precursor is spun (P45) on a first electrode (14), dried (P46) at 400 DEG C for 2 minutes, then annealed (P47) at 750 DEG C to 800 DEG C for about an hour to form a layer (15) of accurately doped BST. A second electrode (16) is deposited (P48), patterned (P49), and annealed (P50) at between 750 DEG C to 800 DEG C for about 30 minutes. Excellent leakage current results if the dopant is magnesium of about 5 % molarity. For other dopants, such as Mg, Nb, Y, Bi, and Sn the preferred dopant range is 0.2 % to 0.3 % molarity. The magnesium-doped material is used as a buffer layer (25, 27) between the electrodes (24, 28) and BST dielectric (26) of an undoped BST capacitor (20).

摘要： A method for fabricating an integrated circuit capacitor (10, 20, 30) having a dielectric layer (15, 26, 37) comprising BST with excess A-site and B-site materials such as barium and titanium added. An organometallic or metallic soap precursor solution is prepared (P42) comprising a stock solution of BST of greater than 99.999 % purity blended with excess A-site and B-site materials such as barium and titanium such that the barium is in the range of 0.01-100 mol %, and such that the titanium is in the range of 0.01-100 mol %. A xylene exchange (P44) is then performed to adjust the viscosity of the solution for spin-on application to a substrate. The precursor solution is spun on a first electrode (P45), dried (P46) at 400 DEG C for 2 to 10 minutes, then annealed (P47) at 650 DEG C to 800 DEG C for about an hour to form a layer of BST with excess titanium. A second electrode is deposited (P48), patterned (P49), and annealed at between 650 DEG C to 800 DEG C for about 30 minutes. The resultant capacitor (10, 20, 30) exhibits an enlarged dielectric constant with little change in leakage current.

摘要： UV radiation is applied to a substrate in a deposition chamber to desorb water and other contaminates from it. A liquid precursor is misted, flowed into the deposition chamber and deposited on a substrate while UV radiation is applied to the mist. The film of liquid on the substrate is dried and annealed on the substrate while the UV radiation is applied to form a solid thin film of a metal oxide. The thin film is then incorporated into an electronic device of an integrated circuit fabricated on the substrate. The application of UV radiation to both the mist during deposition and the thin film after deposition significantly increases the quality of the resulting integrated circuits. The process has been found to be particularly excellent for making BST, strontium bismuth tantalate, and strontium bismuth niobate.
